InfoPath Dev

hello, i have an infopath 2010 form which when submit puts the data in a SP form library and it is all working good. i do not want all the users who submit the infopath form to look at the library. but all the people in organisation are going to submit the requests through the infopath form. the problem is where and how do i host the infopath form inside SP. i want to host it at SC level so that people will submit the form and then it will go to a form library in subsite. did all that and when the user goes to the SC site and sees the form hyperlink. clicks on it and when the form is going to open up it gives this error. "This form cannot be opened because it requires the domain permission level and it currently has restricted permission. To fix this problem, open the form from the location it was published to." i dont want users to go to the location where it was published as i dont want them to look at the entire list. any resolution is highly appreciated. thanks.

 That error is one I usually see when a form hasn't been published correctly. Did you publish the form? You may want to try using a site content type - but the user is still going to need to be able to write to the library in order to submit.

thankyou very much for your reply. yes i have published the form. yes i am looking at site content type. any good article which displays this scenario. thanks.

site content type worked perfectly. now i want to create a new button for the person to click on it and the infopath form downloads. i tried this code. New SOP it says the filename it is opening is right and the from site is right. but after that it gives an error that document could not be created. template for this document library cannot be opened. is there something wrong i am doing.
